When Imagining an Object, It Is Often Difficult to Reimagine

When imagining an object, it is often difficult to reimagine that object as something else. For example, an ambiguous picture could be interpreted as a duck or a rabbit, but when imagining it, people will see only the duck or the rabbit, not both. Hints such as, "Try thinking about the form from the right," can help people to see both aspects of the image. Why would this hint help?

A) This hint alters the image's reference frame.
B) This hint encourages rotating the object.
C) This hint facilitates understanding of the object.
D) This hint acts like a new retrieval pathway for the object.
